SPECIFICATION forming part of Letters Patent No. 231,695, dated August 31, 1880.

Application filed February 20, 1879.

To all whom it may concern.-

Be it known that I, CLARK S. WEST, of the city and county of Worcester, and State of Massachusetts, have invented a new and valuable Improvement in Lamps and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon. I

By reference to said drawings, in Figure 1 thereof a represents the oil-tank, and b the water-tank, connected by posts marked 2' 45, adinittin g free circulation of air between. f represents viaduct of oil to tank, and g the same to water-tan k, while 20 represents disehargepipe of water. The wick-tubes are noted 0 c c passing through the air-space and also the watertank, and d d d d d d represent openingsin the cover of the water-tank around the wicktubes, with lips or short tubes, capable of being packed with any fibrous material, and j j j note the ventilating-pipes of the oil-tank.

In referring to Fig. 2 of drawings, k k represent the ratchet rods, and e e e the ratchets, the former having their hearings on the standards a n a and l 1 l respectively, while at represents a horizontal bar that holds the ratchet-rods in position.

Having described the construction of my lamp, the application of the novel arrangement of its different parts may now be mentioned.

My invention relates more especially to that class of lamps which are used for heating purposes, of one or more burners; and it consists of a novel construction and arrangement of the parts, as hereinafter set forth and claimed, by which a simple and more effective device of this character is provided than is now in use.

In the lamps most generally used for heating purposes, especially kerosene, the temperature of the oil is proportional to the length of ignited wick, and as safety demands that the temperature of the oil be kept within a certain point, the length of ignited wick is limited, and this limits the heating capacity of the lamp.

My improvement'is designed to obviate this difficulty and objection, as well as to render this kind of lamp free from the usual danger of explosion and to that end I make use of a device the construction and operation of which will be readily understood by all conversant with such matters by thefollowin g description:

The oil wick-tubes pass through the airspace and water-tank, and the top of the water-tank is provided with-lips or short tubes, which surround the oil wick-tubes, and are of sufficient size to allow the space to be packed with any fibrous material that will raise the water by capillary attraction. These lips or tubes may be made movable, so as to increase or decrease the length of the oil wick-tubes exposed to the action of the water-packing, thus regulating amount of vapor generated by the heat of the flame. By this arrangement it is impossible to raise the temperature of the oil, however great the extent of ignited wick, but slightly above that of the atmosphere. The device of applying a water-packing to the oil wick-tubes produces results not obtained in any other manner.

During combustion the concentration of the vapor by the packing at the base of the flame prevents the incrustation of the wick and enables the holding of the flame at any required intensity many consecutive hours without any regulation of the wick by the ratchets. The action of the vapor upon the flame renders it odorless, and the humidity of the current of heated air caused by combustion materially enhances its value when used for cooking purposes. V

The simple arrangement of adjusting the ratchet-rods for regulating the wicks permits their easy removal by withdrawing the horizontal bar for the purpose of repair or other cause.

It is known by me that a water-bath or water-basin insulated from the oil-holder has heretofore been applied to kerosene-lamps to counteract the heat of the flame, with auxiliary wicks attached to oil wick-tubes, to prevent melting, to all of which I lay no claim.

I do not intend to claim by language used herein that the application of a water-packing to oil wick-tubes is new or was originated by me, as I am well aware the same has heretofore been used and with intent to produce re sults similar to those claimed by me, but that roe my improvement in the manner of using the The standards n n n ll 6 to support ratchwate-r-packing by a cover to the water-chamet-rocls 7c 70 W, in combination with the hori- 10 her having openings surrounding the wickzontal bar on, the whole being placed directly tubes with lips to hold the packing, is necesupon the Water'ohamber, for uses alleged. sary to perfect and render this class of lamps CLARK S. WEST. useful; but Witnesses:

What I do claim as my invention and as WM. L. WEST,

new is B. F. PARSONS.
